JR -- I think only you can know when you've reached the end of your path, at least the segment that you are on, and realize you have to get on a different road. For me it was when I saw myself doing things out of desperation that I was not proud of. I used to tell my W that ... when certain bad things came to fruition after a long time ... that the dice was rolled long ago. In my case, as tragic and heart wrenching as it feels, I came to believe that the dice was rolled long ago when I decided to marry my W and have children. That is the reality. And I realized that to continue to battle and deny that reality is not mentally and emotionally healthy for myself.
